had a flat battery after i left the car for a month,charged it up but it wont start.Tryed another known good battery and the same.Glow plugs are working but there is no noise being made by the starter.Checked all the fuses in the engine bay and under the rear seat,all good.Only thing i have noticed is that the ignition switch seems a bit slow to return to position 2 after trying to start it.It was VERY slow with the totally flat battery,has it got some kind of motor attached to it?
